Abstract

DISPOSITIVO DE PROCESSAMENTO DE IMAGEM, MéTODO DE PROCESSAMENTO DE IMAGEM, E MEIO DE DISTRIBUIçãO DE PROGRAMA E MEIO DE DISTRIBUIçãO DE DADOS, para tornar possível a geração de uma imagem de forma detalhada a partir de formas rudimentares e, para tanto, trata-se da obtenção de um sub-polígono que tem uma forma tridimensional uniforme a partir de um polígono, onde uma curva de Bezier, como a linha interpolada B~ 12~ que interpola entre os vértices P~ 1~ e P~ 2~ do polígono quadrilátero P~ 1~P~ 2~P~ 4~P~ 3~, é determinada utilizando-se os normais vetores n~ 1~ e n~ 2~, e uma linha interpolada B~ 34~ que interpola entre os vértices P~ 3~ e P~ 4~ é determinada utilizando-se os vetores normais n~ 3~ e n~ 4~; então, os pontos interpolados P~ 12~ e P~ 34~ são determinados nas linhas interpoladas B~ 12~ e B~ 34~, sendo que, ainda, analogamente, uma linha interpolada B~ 13~que interpola entre os vértices P~ 1~ e P~ 3~ e uma linha interpolada B~ 24~ que interpolando entre os vértices P~ 2~ e P~ 4~ são determinadas; então, os pontos interpolados P~ 13~ e P~ 24~ são determinados nas linhas interpoladas B~ 13~ e B~ 24~; da mesma maneira, uma linha interpolada B~ 1234~ que interpola entre os pontos interpolados P~ 12~ e P~ 34~ é determinada, e um ponto interpolado P~ 1234~ é determinado na linha interpolada B~ 1234~. Analogamente, o polígono quadrilátero P~ 1~P~ 2~P~ 4~P~ 3~ é dividido em quatro sub-polígonos, os polígonos quadriláteros P~ 1~P~ 12~P~ 1234~P~ 13~, P~ 12~P~ 2~P~ 24~P~ 1234~, P~ 1234~P~ 24~P~ 4~P~ 34~ e P~ 13~P~ 1234~P~ 34~P~ 3~.IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM DISTRIBUTION MEDIA AND DATA DISTRIBUTION MEDIA, to make it possible to generate a detailed image from rudimentary forms and, for that, it is the obtaining a sub-polygon that has a uniform three-dimensional shape from a polygon, where a Bezier curve, such as the interpolated line B ~ 12 ~ that interpolates between the vertices P ~ 1 ~ and P ~ 2 ~ of the quadrilateral polygon P ~ 1 ~ P ~ 2 ~ P ~ 4 ~ P ~ 3 ~, is determined using the normal vectors n ~ 1 ~ and ~ 2 ~, and an interpolated line B ~ 34 ~ that interpolates between the vertices P ~ 3 ~ and P ~ 4 ~ is determined using the normal vectors n ~ 3 ~ and ~ 4 ~; then, the interpolated points P ~ 12 ~ and P ~ 34 ~ are determined on the interpolated lines B ~ 12 ~ and B ~ 34 ~, and, still, similarly, an interpolated line B ~ 13 ~ that interpolates between the vertices P ~ 1 ~ and P ~ 3 ~ and an interpolated line B ~ 24 ~ that interpolating between the vertices P ~ 2 ~ and P ~ 4 ~ are determined; then, the interpolated points P ~ 13 ~ and P ~ 24 ~ are determined on the interpolated lines B ~ 13 ~ and B ~ 24 ~; likewise, an interpolated line B ~ 1234 ~ that interpolates between the interpolated points P ~ 12 ~ and P ~ 34 ~ is determined, and an interpolated point P ~ 1234 ~ is determined on the interpolated line B ~ 1234 ~. Similarly, the quadrilateral polygon P ~ 1 ~ P ~ 2 ~ P ~ 4 ~ P ~ 3 ~ is divided into four sub-polygons, the quadrilateral polygons P ~ 1 ~ P ~ 12 ~ P ~ 1234 ~ P ~ 13 ~, P ~ 12 ~ P ~ 2 ~ P ~ 24 ~ P ~ 1234 ~, P ~ 1234 ~ P ~ 24 ~ P ~ 4 ~ P ~ 34 ~ and P ~ 13 ~ P ~ 1234 ~ P ~ 34 ~ P ~ 3 ~.
